Aux fan harness/ coolant temp sensor location
 

Hi guys, I believe that I have the correct one but to make sure. Facing the front of the car under the front black plastic trim piece,
towards the driver side is a sensor screwed into the manifold. is this the one that is tied into the aux cooling fans ?.

I'm pretty sure it's the 2 prong sensor in the same vicinity the you metioned.
